abstract = "Medical images are often expensive to acquire and offer limited
use due to legal issues besides the lack of consistency and
availability of image annotations. Thus, the use of medical
datasets can be restrictive for training deep learning models. The
generation of synthetic images along with their corresponding
annotations can therefore aid to solve this issue. In this paper,
we propose a novel Generative Adversarial Network (GAN) generator
for multimodal semantic image synthesis of brain images based on a
novel denormalization block named BOundary and sub-Region
DEnormalization (BORDE). The new architecture consists of a
decoder generator that allows: (i) an effectively sequential
propagation of a-priori semantic information through the
generator, (ii) noise injection at different scales to avoid
mode-collapse, and (iii) the generation of rich and diverse
multimodal synthetic samples along with their contours. Our model
generates very realistic and plausible synthetic images that when
combined with real data helps to improve the accuracy in brain
segmentation tasks. Quantitative and qualitative results on
challenging multimodal brain imaging datasets (BraTS 2020 and
ISLES 2018) demonstrate the advantages of our model over existing
image-agnostic state-of-the-art techniques, improving segmentation
and semantic image synthesis tasks. This allows us to prove the
need for more domain-specific techniques in GANs models.",
